You will observe the orbits and you have to determine how many planets are in the habitable zone and how many are orbiting successfully. Based on the mass of the star and the placements of the planets, planets may swerve into the star and vanish, collide with each other and vanish, float out of orbit, or all orbit successfully. You will record this information and each planet's orbit in your data table for each trial. If the mass of the sun is 1x, planets will fall into the habitable zone if I place a planet in orbits (Orbit=1,2,3,4,5,6,7,8), and all planets will orbit the sun successfully.
If the mass of the sun is 2x, planets will fall into the habitable zone if I place a planet in orbits (Orbit=1,2,3,4,5,6,7,8), and all planets will orbit the sun successfully.
If the mass of the sun is 3x, planets will fall into the habitable zone if I place a planet in orbits (Orbit=1,2,3,4,5,6,7,8), and all planets will orbit the sun successfully.

A sample of a pure substance with a density of 3 g/mL is separated into two pieces. One piece has a mass of 50 g and the other piece has a mass of 25 g.
What is the density of the larger piece?

Answers

Answer: The two pieces have the same density of 3g/mL.

Explanation: the density won't change based on the size or amount of the substance. the density is pre-set (for every X there is y weight, this is always constant).

Example:

A brick of salt measuring 10.0 cm x 10.0 cm x 2.00 cm has a mass of 433 g. What is its density?

Step 1: Calculate the volume
